A researcher wanted to see if a newly developed study session program at his university would help increase grade point average (GPA) for a population of students. The average GPA for these students is known to be 2.98. Assume the population standard deviation for students who complete the study session program is known to be 0.6. A random sample of 15 of these students were enrolled in the program for a full year and then their GPA was recorded. We conduct the appropriate hypothesis test and we determine the value of the corresponding test statistic to be 1.73. What is the corresponding p-value?

Suppose the University of Memphis advertises that its average class size is 35 or fewer students. A student organization is concerned that budget cuts have led to increased class sizes and would like to test this claim. A random sample of 38 classes was selected, and the average class size was found 36.9 students. Assume that the standard deviation for the class size in the college is 8 students. Using α = 0.01, test the student organization's claim. To test the claim: • Use the critical value approach • Use the p-value approach • Explain in your own words how Type I and Type II errors can occur in this hypothesis test

The average GPA of a random sample of 11 college students who take evening classes was calculated to be 3.15 with a standard deviation of 0.06. The average GPA of a random sample of 23 college students who take daytime classes was calculated to be 3.2 with a standard deviation of 0.02. Test the claim that the mean GPA of night students is smaller than the mean GPA of day students at the .025 significance level. Claim: Select an answer which corresponds to Select an answer Opposite: Select an answer which corresponds to Select an answer The test is: Select an answer The test statistic is: t = (to 2 decimals) The P-value is: Select an answer Based on this we: Select an answer Conclusion There Select an answer appear to be enough evidence to support the claim that the mean GPA of night students is smaller than the mean GPA of day students.

The mean age of graduate students at a University is at most 31 y ears with a standard deviation of two years. A random sample of 15 graduate students is taken. The sample mean is 32 years and the sample standard deviation is three years. Are the data significant at the 1$\%$ level? The p-value is $0.0264 .$ State the null and alternative hypotheses and interpret the $p$ -value.
